This function simplifies the procedure for estimating the background for several detector banks by a multiple call of do.fit
. Other relevant parameters are set to: stdev=FALSE, scale=NA, p.bkg=.5
.
For neutron scattering, the incoherent background exhibits a broad peak at low Q and decays gradually at higher Q. Hence, we suggest to use different numbers of knots for the low- and high-Q regions. See BBEST-package
for details.
A list of elements. Each element contains a return value of do.fit
for the corresponding data bank.
